    Notes: Abstract The complex (1) has been prepared and its structure determined. Complex1 is the first stable thioether derivative of a metal carbonyl containing only cobalt as metal. It crystallizes in the monoclinic P21/c space group, witha = 13.975( 4 ),b = 11.363( 3 ),c = 14.686(2)A,β = 112.25(2)°,V = 2158.5(7)A3.Z = 4. The solution using direct methods and the anisotropic refinement of all nonhydrogen atoms led toR = 0.039,wR = 0.041 for 3296 reflections with F〉 4.0σ(F) Analogous but less stable complexes are formed with 1,6-diphenyl-2,5-dithiahexane and the crown thioether 1,4,7-trithiacyclonane, the latter functioning either as a bidenlate or a tridentate ligand.

    Synthesis of Co3(CO)7(μ-η3-Allyl)(μ3-X) Complexes (X=S, Se) and Structure of the Selenium Derivative (2000)

    Notes: Abstract The complexes Co3(CO)9(μ 3-X) (X=S, Se) can be reduced to the corresponding anionic species [Co3(CO)9(μ 3-X)]−, which react with allyl bromide to give Co3(CO)7(μ-η 3-C3H5)(μ 3-X) (X=S, Se). These are the first two cobalt complexes containing the bridging μ-η 3-allyl ligand. The structure of the selenium complex was determined by X-ray crystallography. Crystal data for Co3(CO)7(μ-η 3-C3H5)(μ 3-Se) are as follows: space group P21/c, a=9.051(2) Å, b=8.102(2) Å, c=21.27(4) Å, β=93.82(3)°, Z=4, and R=0.0565 for 2491 observed reflections.
